✦ Synopsis

A theoretical model is presented that may be usefully employed to establish the limiting geometric and hydrodynamic conditions for a thin-layer cell to attain 100% coulometric efficiency. The thin-layer cell, based on a glassy-carbon electrode 5 cm in length (the flow path) and 2 mm wide was tested for three different channel heights at high and low flow rates (1 and 60 ml/h) using 1 mM potassium hexacyanoferrate(I1) as the electrochemical probe in conjunction with a flow injection system.
